I covered this tool earlier here: http://mileyja.blogspot.com/2011/11/chinmay-patel-releases-crmxpress-soap.html
But I thought I would let everyone know that Chinmay Patel's Smart SOAP Formatter solution does work for CRM Online. Check out the video here: http://www.crmxpress.net/blog/Blog/post/2011/12/08/Releasing-CrmXpress-SmartSoapLogger-v10.aspx
If you don't remember what it does it is basically what I wanted my SOAP formatter solution to turn into. You write your web service code in .NET and it connects to your server and just magically converts it to a jscript for you and also shows you the SOAP packets if you like too.
Have a great day
